Statistical Approach for the Determination of the Stereoregularity of Optically Active Propylene–CO Copolymers

A two‐parameter statistic model was applied to analyze the NMR spectra of a series of stereoregular propylene–CO copolymers synthesized by catalytic polymerization in the presence of various transition‐metal complexes containing chiral ligands. The concentration of the different pentads, estimated to be recognizable in the spectra, was determined. A tentative assignment of the nature of the different peaks composing the signal of the C?O group in the ¹³C‐NMR spectra is proposed.
